Hi, actually i'm working on a new isntallation, so i have installed CUCM 7.1.3 and CUPS 184.108.40.20600-17, users at CUPC can login but the status is stuck at off line and cannot be modified, i cannot place calls between cupc's either chat messages.
Under server status i see green the session server, tftp config, presence, softpfone, and ldap, under the system troubleshooter all items are green but the deskphone control, meeting notification and inter-cluster troubleshooter.
Already configured proxy domain under service parameters and federation routing CUP FQDN, also under security configured ACL for incomming and outgoing for All permissions.
attached you will find the logs
You haven't enabled detailed logging on CUPC. Thus there's not too much information in the logs.
If presence is connected but CUPC stuck offline, that's because it didn't received SIP NOTIFY from CUPS.
90% chance a firewall was blocking incoming traffic to CUPC on port 50001 - 50063.
10% chance the MER (Method Event Routing) was somehow misconfigured up on CUPS.
I'd recommend you do a packet capture and see if CUPC received any SIP NOTIFY.
